OVERLAND PARK, Kansas - A Johnson County jail official says the man accused of killing three people outside of Jewish sites near Kansas City is Frazier Glenn Cross.

The official confirmed that Cross is the suspect in Sunday's attacks in Overland Park. He spoke on the condition of anonymity because he wasn't authorized to discuss the case publicly.

Public records show that the 73-year-old Cross also goes by the last name Miller. The Southern Poverty Law Center says he has long been an outspoken white supremacist and was once a "grand dragon" of the Carolina Knights of the Ku Klux Klan.

The group reports on its website that it spoke to Miller's wife, Marge, by phone Sunday and she said police told her that her husband had been arrested in Sunday's attacks.
